i Application led September 24, 1926. Serial No. 137,429.

This invention relates to articles ofpersonal wear and adornment, with special reference to cuit' buttons, and particularly to those of a separable type.

It is one object of the present invention to provide a button of this class which is resistant to attempts at separation by force exertedto pull or push the parts in opposite:

directions, the parts being detachable only when its interior elements are moved into a del'nite position by exerting pressure on one of the button faces, one hand only being required.

A further feature is in the provision of a separable culi' button having level, smooth and unbroken faces at each end, alike in appearance except that on the button face which is to be pressed `inwardly to separate the parts there can be some distin ulshing mark or indication, easy to embelhsh with various designs and having no projection to catch and interfere with the clothing or any other object.

By the elimination of a knob or other projection extending outwardly beyond the plane of the front face of the button `which are common to other cuff buttons of this type, the danger of accidentally opening the bjuttonwhen the arm of the wearer is leaned upon a desk, table, arm chair or other object, and thereby de ressing the knob which disengages the clutch inside, is obviated.

As is obvious, the absence of any projection increases materially the scope of designs or other ornamentation and also makes it possible `to ornament both button faces identically, thereby decreasing the cost of manufacture and improving the appearance of the article.

The elimination of any such projection is a further advantage, because when the faces are of similar appearance it is not necessasry to give any time or care to making certain that uniformity of appearance is attained by having the said projections both face either outwardly or inwardly in each cuff. In the device of this application as the faces are similar, the sections with the liXed or depressible faces may be inserted through the button hole in either side of the cuit' and perfect uniformity of appearance will be attained.

Another aim is to produce a highly attractive button, capable of tightly clamping the material through which it is passed, thus preventing loss by displacement, but permittine ready removal at will.

hese several objects are attained b the novel construction, combination an arrangement of parts hereinafter described and shown in the accompanying drawing, forming' a material part of this disclosure, and in which z- I1`ig. l a general illustration showing the manner of removing the button with relation to a conventional cuit'.

Fig. 2 is a greatly enlarged longitudinal sectional view of an embodiment of the in vention.

Fig. 3 is an end view of the button partially broken away.

Fig. 4 is a similar view looking from the opposite end.

Fig.. 5 is a side elevational View of the button as disengaged.

As will be noted in Fig. 5, the button consists of two distinct members, A and B, the latter com rising a face 10, ornamented in any desiree manner and provided with a backing 11, of slightly' less diameter.

The extending annular edge of the tace element l() is seated on the outer surface of a hollow ring or bead 12, the openings therethrough engaging the periphery of the backing 11 and its inner edge 18 engages over an outturned expanded edge of a bellshaped casing 14 having a short, contracted cylindrical inner end 15.

Engaged in the casing end l5 and extending slightly into its flared portion is a sleeve 16 formed with an outwardly inclined iange 17 terminating in a closed circular bead 18, the same constituting one of the abutting elements of the button member B.

Resting on the inner face of the backing 11 are the forked ends 19 of -a trilobed flat spring 20 spaced by its ends from the backing plate and seated on the main central portion of the spring is the back of a second fiat spring 21, also having three inbent extending prongs 22 reaching normally into the space enclosed by the sleeve 16, this last named spring 21 being held in position by prongs 23 on the spring 20, as best seen in Fie. 2,

'he other member A consists of a similar face 25 having an offset annular flange 26 at its periphery in which is a circular backing plate 27.

A bead 28, similar to that previously described, slidably engages over the flange 2G at its outer edge and its inner edge 29 is fitted overthe expanded end of another bellshaped casing 30, having an inner cylindrical end 31 in which is fixed a sleeve 32 formed on an outwardly inclined flange 33 terminating in a circular bead 34, opposed to the mating bead 18 of the other button member. y l

Fixed in the sleeve 32 is a plug 35 having a. chamber 36 in its outer end and provided with a bulbous projection 37 connected by a contracted neck 38.

Fixed to the inner side of the backing plate QT is a cylindrical rod 39 extending slidably through the plug 35 and its projection 37 to ab-utthe inner side of the spring 21 and encircling the rod is a coiled compression spring 10, one end abutting the backing plate and the other the bottom of the recess 36.

In operation, when it is desired to conneet the two members, the extending portion of the plug 35 and the bead 3&1. are passed through-anV opening in the article to which the button is to be attached, and the mating member B pressed over the plug from the opposite side of the article.

Contact of the bulb 37 with the arcuately curved spring fingers or prongs 22 causes the socket formedby them to recede, depressing the spring 20 until the ends of the prongs clear the sleeve 16, permitting them to expand and thereafter grip the bulb securely.

Attempts at separation are unavailing, except by exertion of sufficient force to cause destruction, due to the fact that the bulb 37 cannot pass out of the socket fingers, by reason of their inability to open, being held rigidly constrained by the sleeve lf3 surrounding their outer ends.

.The button is however readily separated by pressing the face 9.5 inwardly, causing the rod 39 to press the spring 20 and attached socket rearwardly, clearing the sleev-e whereupon the button is forced apart by continued pressure on the face 25.

i/Xlthough I have described my improvements with considerable detail and with respect to certain particular forms of my invention, I do not desire to be limited to such details since many changes and modifications may well be made without departing from the spirit and scope of my invention in its broadest aspect.

I'Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent is z- 1. A separable cutt1 button eonlprising a pair of inwardly convergingv members having level fixed and movable flat faces respectively, means for retaining said movable face normally extending uniformly with the fixed face, cooperative resilient finger means to cause positive interengagement of said members whereby they are held inseparable, and means actuated by depression of said movable face to release said engaging means.

2. A separable cuff button comprising a pair of inwardly converging members having level fixed and mov*L ble fiat faces respectively, a spring supported yieldable socket cz rried by the fixed faced member, a sleeve to prevent said socket from expanding when pressed outwardly by its spring support, a bulbous element carried by the other member to engage in said socket and resist forcible separation, and means actuated by depressing the movable face of the last named member to retract said spring supported socket and release said bulbous element.

3. A separable cuff button comprising a pair of members having level uninterrupted fixed and movable fiat faces respectively, a spring to retain said movable face extended, a converging casing reaching inwardly from each member having a clamp member at its inner end, said clamp members being 'juxtaposed when the button is in operative position, a resilient support on the inner side oll said fixed face member, a split spring socket larried by said support, means to prevent expansion of said socket when extended, a bulbous element. carried by the other member adapted to engage in said socket under pressure, and a rod passing through said bulbous element to retract said support, said rod be ing actuated by said movable face.

In testimony whereof I have hereunto affixed my signature.
